I CAST...! Animal Shapes, summoning different elemental animals! 2d20 animals in total! 25! The lower the roll, the more deadly the creature! (aka 1 gets max CR like Tiamat or a tarrasque, 20 summons 20 harmless creatures)

Edit: Original roll was a 19! So 2 Ancient Gold Dragons made of fire are summoned!

I CAST PUNISHMENT FOR POTENTIALLY MANIPULATED DICE ROLL RESULTS! 50 SAND STORMS APPEAR！

 I CAST...

YOU DIDN'T CAST A SPELL! PERISH!

*5 seconds after I say this, a comically large bomb begins falling from the sky with a giant red timer strapped to it and various exposed wires.*

I cast Lion and Tigers and Bears.

All of you are surrounded by 7 lions, tigers, and bears. All of which are loyal to me.

With my bonus action, I cast Bidoof. The next person to post is magically turned into a Bidoof.

I cast D&D logic.

In D&D you cannot use a bonus action for magic.

 I CAST... *LOUD INCORRECT BUZZER*

Some spells have casting times of bonus actions. Although apparently you can't cast multiple levelled spells in one turn, didn't know that before, you can in fact use a bonus action for magic.

(You take 38 psychic damage)

For my bonus action, I CAST... CAN TRIP!

All cans in existence automatically fall over.

 I Cast what I meant.

During a Turn, you can only use magic once. So you can not use it as a action than a bonus action.

I cast Ultimately Fireball, a large meteor the size of the heavens comes down and smites this planet.

Everyone must make a DC50 Dexterity Save or be smited.

I turn this board into a rulebook where anything that gets said here is the law.

 I CAST... *EVEN LOUDER INCORRECT BUZZER*

Still incorrect. Also, even Crunch has cast one spell then another as a bonus action.

 1. I have never heard anyone call a thread a board. We need to revive the D&Dictionary, lol.

2. You can just make a thread for that instead of converting this one, although I think I made one called "New Rule Every Post" but it died.

3. Nuh uh

As a bonus action, to counteract me making two arguments in one turn, I CAST... SUNSHINE AND RAINBOWS! :DDDDDDDDDDDDDDDDDDDDDDDDDDD
